4 INVENTOR. F By Czar/c5 Zqfie/ ATTORNEYS carried prefer-ab common to wood carving machines. In thedrawings I have shown electric motors although I ma employ com ressed air 'or'any" other suitab e type as t e occasion Ina demand. I have also provided handles 30 on the tool carrying board 19 by means of which I am enabled to control andmove the various parts of the machine andtolfollow the tracer over. the carving being reproduced. As noted above, the tool carrying board 19 is hinged to the member 18. Thispermits the cutting tools 27 and the tracer 23 to be always held in a. vertical osition regardless of. the angle of irame-wor 11. y,

A. table or support is provided beneath the machine on which are secured the ing A to here roduced and the iecesof material A. to carved. These pieces A are securedbeneath the cutting-tools 27 relativel the same position as the car vi ng Aistotietracer23. v A;counterwei ht. 36 is v Iy by the real 1.5 of the horizontal frame-work 11 and is of such weight as to balance the weight of theouter-end of the framework 11 and make the opera;- tion oi nachindresponsive to a slight effort on the part of operefpr;

As will be noted frorngthe above descripll on the lower end of the pivoted verticali'rame-work l. The amount of this movement is determined by the length of the vertical members 6 on the frame-work 11.

By means of this construction it is notnecessary to make thetable 35 movable as is required in most/carving machines.

I have also provided a sim lified means for drivin the cutting tools tiereby eliminating muai of the trouble and inconvenience encountered in belt driven machines and by means of the individual drive for the cutting tools I am enabled to use as many of the tools at one time as are required. By employing individual drives for each cuttin tool, I eliminate the use of belts, ulleys on cross shafts and their numerous ttin s, and also the use of a large-and power ll. motor as the motors employed are small and as som et Z .7 136 3 horizontal tion, I have provided a. wood carvin ma b9 horizontal frame-work hi -tain thecutting tools in a vertical position to the material being worked on; ran-Teen hold the tools at an angle when y it 15 neccssarvtodg so.

In v'i' 'w ofth'e 'above description it will be noted that I have produceda simplified form. of .carving machmmpne having fewer nd M l ;;fi l -,-*e as.-its 33in gidividualhdriveu It is (fioomj parativ invve' 1: et itisri i an gstrongenod to reta n: its ali I on? which .isnecessary fin machines;of,; 7 character.
